Jenkins build agents disconnecting

Question

I am having an issue with Jenkins build agents seeming to disconnect and fail to run jobs randomly. The build agents (3 of them) are Windows VM’s running in Azure. Jenkins is configured to run as a service on each build agent. The Jenkins server is also an Azure VM running linux. Hoping someone in this group might have some ideas. Below is a stack trace of the error. Many times if you attempt the job again it will run successfully.

The Jenkins slave on windows is running as service or process ? And what is the method or way to setup the slave ? — error404, Mar 12 '19 at 15:22
@yashbagarka it is running as a service on Windows. Here is the config for the client: C:\Program Files\Java\jre1.8.0_201\bin\java.exe -Xrs -jar "%BASE%\slave.jar" -jnlpUrl https://redacted.eastus2.cloudapp.azure.com/computer/inserternode1/slave-agent.jnlp -secret redacted — avidgoffer, Mar 12 '19 at 16:28
